My current system is H4. Car is 98 civic. When you turn on high beams the low beams turn off.
Now I am adding a bixenon projector which uses an H1 bulb.
So I need this setup:
The bulb stays on, both on high and low beams.
The high beam wire triggers the cutoff in the projector.
I can just join the high and low beams because it will mean that the cutoff solenoid always get power.
I dont want to use relays and want to keep it clean. I was thinking of using a diode between high and low beam wires but if you have a better solution let me know.
